To all 'whom -z't mtzy concern:

Be it known that I, Gnomes BiNoN, a citi zen of France, and residing .atlG Place de la. Rpublique, in the cifty of Paris, France, having invented anew aud-`useful Automatic Carburetorl for Engines with Combustionv by Explosions, doY hereby declare that the followin is a full, clear, and er:L act description o the same.

My invention relates to spraying engine carbureters and is characterized by the fact that it insures steady and uniform carbureting for varying loads on and speeds vof the engine. K p l The invention has for its object to provide an apparatus comprising the combinalet' disposed beneath the normal level of' the 2 tion of devices to serve the` following pui poses: (1) A spraying device with air infuel for injection of the liquid into a spray- .ing chamber. (20) An arrangement of a restricted suction space where the spraying device is disposed, the said restrictedlsud' tionspace having for object to give a strong depression around the spraying device by the suction during the.working of the ino-- for. (3"1 A, small reservoir placed above the jet anti con'uuunicatingvat its base with the external air through a circular channel and air admitting pipe open to the am- .bient air;'said reservoir -and pipe having their extremities situated at a height above ,the normal level of the fuel-sothat no flow will occur when the carbureter is inoperative. (4) A pipe connecting the reservoir above the spraying device/ to the suction chamber, between-the throttle valve. and the' motor, facilitates the spraying vwhen reducing the speed or load on the motor.

In the accompanying. drawing, Figure l is a side elevation of the'upper portion of the carburetor, Fig. 2 is vertical section of the complete carbureter.

a indicates a device whereby avconstant level of liquid is kept in the spraying jet independently of the varying quantity necessary for the working of the engine.

Zi is a suction pipe wherein -carlnrretintT takes place through the action of the spraying device c placed centrally in' the restricted suction space 1. The suction space or chamber may be jacketed so as to be warmed either by Water or by hot gases from the engine or by other beating medium adapted to be circulated through said jacket.

The spraying device c is placed so that itsv orifice 2 which regulates theconsumption ofcarburant, is below thenorma'l level.

In order to prevent the flovvingof the carburant through the orifice ornozzle 2 when the carburetor is not-Working, a reservoir 3 is placed above said orifice of the jet, the diameter of the reservoir 3 being greater than the diameter of the orifice of `the jet, and its height greater than the level difference li., between the orifice of the jet and the normal level. Sai-d reservoir 3 communicates at its base with the air through an opening 5, ring shaped chamber or canal 4, and diagonal canal or passage 6,- whichextends a little above the constant level of the carburant, so that no flow will occur when the carbureter is inoperative. Y

d a device for the admission of the explosive gases for charging the engine, say a. valve or `cock as represented in the drawing; it may be fixed to the carbureter byA screws'` 8 While the Harige 7, serves forv fixing and carrying the whole carbureter.

A pipe 1l leading into the suction pipe between the throttle valve and the motor,`is put in communication with the reservoir 3, the object of said pipe being to convey the depression actually taking place. in the slction pipe and thus facilitate the spraying when the inotor slackens. The spraying will occur in the jetthrough orifice/2. Thel reservoir 3 and the pipes or canals connected thereto will prevent flooding, help the starting and facilitate suction when the m0! tor slaclrens.

The working of the apparatus thus constructed is as follows: The carburant Coming through opening 9 is kept by theoat in a at an always constant level, and passes through passage l0 below the sprayer c. In the inoperative period, the liquid level will be established in the float chamber a, in the space 3 above the orifice of the jet 2, and in Vthe air canal 6, the motor will therefore start easily and immediately owingto the supply of liquid fuel contained in the said canals and which will be sucked at the first y turn of the crank. The motor turning no rtion to the depression produced by the suc` tion in'the restricted space; l have therefore placed the orifice 2 below the normal level lll) so that the liquid fuel will bend-to fill the jet and furnish automatically a small quantity 0f carburant, fhereby correcting irregulari'ties occurring in ordinary ca-rburetcrs. During slower working, the depression of the suction above the orifice 2 is facilitated by the pipe Il connected to reservoir 3.

It iS to be understood that thc form and details of the apparaus shown in the draw ing muy be varied Within reasonable limits.

I claim- In a carbureter for internal combustion engines the combination with a jet placed below the norma-l level of the 'fuel and superposed by siV reservoir preventi the' flooding of the liqid fuel, the Whoe lo` cated in a restricted Space of the suction pipe, of a system of canals communicating with the said reservoir and leading, one to the Suction climbcr liciwccn the throttle valve and the mot-or and the other to the ambient nir for the purposes given in the specification, all sulismntially as set forth.
